intersecting paths by providing improved resilient clamping means whichis adapted to :maintain frictional engagement between the fixtureandthemounting therefore so .asto enable said vfixture to be positionedat any convenient location along its path.

Another object of my present invention is to provide a shiftableelectrical lighting fixture in which the electricalvcircuit'may bemaintained during the shifting of a light withoutnecessitating the useof flexible conductors and the like, and to'this endT propose to providea'contact element along which the lighting fixture may be moved.

1 These and other objects vwill be more apparent from the followingdetailed description when consideredin connection with the accompanyingdrawings, wherem- Figure' l is a front view of my cabinet @with certainparts broken away;

. Referring to the drawings more particularly, I have? illustrated anddescribed my invention as adapted to a cabinet 7 of the bathroomtypeprovided with a hinged'door carrying a mirror. I It will beapparentthat-the mounting ofthisinvention might be adapted nto: various otherpurposes. This cabinet 7 is provided with the usual body having shelvesLStherein and a door 9 mounted on hinges "11 ;;to swing to: open andclosed'position; The

rear of the cabinet is provided with an open- :ingi1l2ithrough. WhlClipasses electric WlIlIlg 13 connected to a source (not shown), ofelectrical current. This wiring 13 is led through a tubular guard 14 toa compartment 15 formed between the front of the door 9 and a partiti on16 carried thereby in inwardly spaced relation. This guard is pivotallymounted for horizontal swinging movement on a vertical pin 17 attachedto the door within the compartment 15 and extends through the front wall18 of a small compartment 19 in the upper end of the cabinet and thepartition 16, suitable openings being provided therefor in said wall andpartition. The wiring 13 after passing through the tubular guard 14passes outof an opening 19 for connection to a movable fixture 21,suflicient slack being provided in said wiring within the compartment15sothat said fixture may be moved, as will be hereinafterdescribed,without impairing the connection. The guard 14 acts to protectthe wiring during the opening and closing movements of the door tothereby prevent the wiring from being caught or pinched during suchmovements.

The door of the cabinet is provided with'a 'mirror 22 and the fixture 21includes an electric lamp 23 adapted to illuminate the face of a personbefore the-mirrorand enable the mirror to reflect an image of the facethus illuminated. The lamp is mounted so that it can be convenientlyshifted along the margin of theinirror into various positions of adjustment to facilitate persons of various heights seeing themselves inthe mirror and to facilitate a person seeing any desired'portion of lllSface more clearly. In this embodiment the lamp may be shifted verticallyalong the margin of the mirror frame on either side thereof orhorizontally along the margin at the bottom of the mirror frame, thevertical axis of the lamp being rigidly maintained at all times. i

To that end I provide a slotted track24 extending from a position midwayup on the margin of the mirror frame at one side thereof downwardly to alower corner of said frame horizontally across the lower margin of saidframe to the opposite lower corner and upwardly to a correspondingposition on the other side of said frame. This track 24 includesvertical guide-ways 25 and 26 which intersect a horizontal guide-Way 27at its respective opposite ends. The guide-ways 25 and 26 are providedwith a vertically elongated slidable carriage 28 and 29 respectively.

slidable carriage 31 is capable of sliding directly in the guide-way27and of being car ried by the carriages 28 or 29 in their respec-' tiveguide-ways. The carriage 31 rigidly supports the fixture 21 includingthe lamp 23 and comprises an integral outwardly extending sleeve 32, theouter end of which is screwed in. an, angular'ly disposed lamp fitting33 which together with the lamp 23 and a socket 34 at the upper end ofsaid fitting forms the fixture 21. The wiring 13 passes from thecompartment 15 through the sleeve 32 and the fitting 33 to the socket34.

As the fixture 21 is moved horizontally in the guide-way 27 the upperand lower sides of the carriage 31 co-operating with said guideway willmaintain the axis of the lamp 33 vertically. The lower portion of eachof the carriages 28 and 29 is cut away to receive the carriage 31 whichis of considerably less thickness than either of said first mentionedcarriages. The carriages 28 and 29 are each provided with a horizontalguide 35 adapted to extend into a co-operating groove 36 in the carriage31 to maintain the latter in horizontal position at the intersections ofthe horizontalguide-way with either of the vertical guide-ways tothereby maintain the vertical axis of the lamp at this intersection andassure alignment of the carriage 31 with the carriage 31 iscarried byeither of said first mentioned carriages. Without the verticallyreciprocablecarriages 28 or 2 9 the carriage 31 when at either end ofthe guideway 27 preliminarily tobeing moved up- Wardly in one of thevertical guide-ways'or preliminarily to being moved from one of saidvertical guide-ways into the'horizontal guide-way would not be rigidlyheld'in horizontal position to thereby rigidly maintain a vertical axisof the lamp and assure alignment of the carriage 31 withjthe guide-wayin which'it is desired to moveita For this reason the carriages 28 and29 greatly facilitate the transfer of:the carriage 31 from thehorizontal guide-way to either of the vertical guide-ways or vice versaand thereby enable the lamp fixture to be more conveniently adjusted.

Surrounding the sleeve 32 is a coiled spring 39, the inner end of whichengages a circular shoe 41 also surrounding said sleeve and disposedbetween the fitting 33 and the track 24. The outer end of this spring 39engages the bottom of a recess 42 formed within the fitting 33 for thereception of said spring and the inner end'of said spring yieldinglyholds the shoe 41 against the track to thereby automatically maintainthe lamp fixture 21 in adjusted position.

Referring now to Figure 7. it will be seen bushing 44 is ayieldablecontact finger 46 which is yieldably maintained in contact witha suitable contact strip or bus bar 48 through the agency 7 of asuitable coiled spring 50. The contact finger 4:6 is electricallyconnected with and housed within a metallic sleeve 52 which is connectedto the terminal of a conductor 5a, which conductor is connected with thelamp proper. For purposes of more clearly 'llustrating the arrangementof the device, the lamp 23 is shown diagrammatically. is groundedthrough the lamp frame 33 and the door frame 9 as clearly shown inFigure 7. It will thus be apparent that the lamp fixture may be movedfrom one position to another within the passageways without disruptingthe contact between the finger 46 and the contact strip 48. I

It will be apparent that my invention is applicable to mountings otherthan the specific cabinet mounting also be understood that my improvedmounting enables a lighting fixture to be adjusted from one position toanother through an angular path of movement with a minimum amount ofeffort and there will be no tendency for the fixture to wabble. In otherwords, the fixture in moving from one path to another, cannot oscillateabout its axis and the carriage members also assure the proper alignmentof the fixture when shifting from one guide-way to the other. In myco-pending application Serial No. 190,538, filed May 11, 1927, relatingto wall cabinet,I have disclosed a shiftable lighting fixtureofthe typewhich may be readily equipped with carriage devices of the designdisclosed in the present application.
